Question

Choose the number sentence that shows the identity property of addition.

A.
122 = 61 + 61
B.
62 = 1 + 61
C.
61 = 0 + 61

Answer 1

The answer is C.

Explanation:

The identity property of addition is a number (in this case, 61) plus 0 equals 61. This shows that the number doesn't change.

I hope this helped! :-)

Answer 2

For this case we have that by definition, the property: Identity element of the zero-sum establishes:

`a + 0 = 0 + a = a`

Example:

`-4 + 0 = -4\\7 + 0 = 7`

The number "0" is the only element that retains the identity in the operation of the sum.

Thus, the equation:
`61 = 0 + 61` is an example of this property.

ANswer:

`61 = 0 + 61`

Option C
